Modal Pushover Seismic Analysis of Sac Buildings excluding Gravity Loads
Evaluated is the accuracy of the modal pushover analysis in estimating the seismic demands for six SAC buildings, excluding gravity-loads and P-delta effects. These results are compared with those obtained by nonlinear response history analysis and three force distributions in FEMA-273.
متن کاملA Target Displacement for Static Pushover Analysis to Estimate Seismic Demand of Eccentrically Braced Frames
A main challenge for performance-based seismic engineering is to develop simple, practical and precise methods for analyzing designed buildings and assessing existing structures to satisfy considerable performance objectives. Pushover analysis is a simplified nonlinear analysis technique that can be implemented for estimating the dynamic demands imposed on a structure under earthquake excitatio...
متن کاملModal Pushover Analysis of SAC Buildings
The nonlinear static procedure (NSP) or pushover analysis in FEMA-273 [FEMA, 1997] has become a standard procedure in current structural engineering practice. Seismic demands are computed by nonlinear static analysis of the structure, which is subjected to monotonically increasing lateral forces with an invariant height-wise distribution until a target displacement is reached. None of the curre...
متن کاملan iterative process for pushover analysis of double unsymmetric-plan low- and medium-rise buildings under bi-directional excitation
double- unsymmetric-plan medium-rise buildings subjected to bi-directional seismic excitation are complex structures where higher-mode effects in plan and elevation are important in estimating the seismic responses using nonlinear static or pushover analysis. considering two horizontal components of the ground motions makes the problem more intricate. this paper presents a method for nonlinear ...
متن کاملEvaluation of Modal and FEMA Pushover Analyses: SAC Buildings
This paper comprehensively evaluates the Modal Pushover Analysis (MPA) procedure against the ‘‘exact’’ nonlinear response history analysis (RHA) and investigates the accuracy of seismic demands determined by pushover analysis using FEMA-356 force distributions; the MPA procedure in this paper contains several improvements over the original version presented in Chopra and Goel (2002). Seismic de...
